With Copeland Scroll™ compressors there are three ways to achieve capacity modulation to fit every application need.

Copeland ScrollVariable SpeedThe Copeland Scroll Variable Speed solution for heat pump applications with capacity modulated compressor developed to deliver outstanding performances and reliability, both in new buildings and boiler replacement scenarios. The new ZHW and ZPV Copeland Scroll compressors feature a state of the art brushless permanent magnet motor matched with a highly efficient drive. ZHW benefits from Enhanced Vapor Injection technology for best seasonal efficiency.

Copeland Scroll Digital™ CompressorsThe Copeland Scroll Digital compressor increases system efficiency by precisely matching compressor output to your heating or cooling needs. Because its capacity modulation between 10% and 100% can be achieved using one compressor, Copeland Scroll Digital is perfect for buildings or systems which experience widely varying loads or where tight temperature and humidity control are needed. Since they were developed in 1993, Copeland Scroll Digital compressors have been working in this field with proven reliability all over the world.

Six to eight compressors per unit can be used, which means, depending on even or uneven combination, up to 12 capacity steps available to match the load by cycling the compressors on and off.

Multiscroll Copeland assemblies are the ideal choice when system flexibility and reliability is needed, in particular for commercial applications. System designers, consultants and end users can already benefit from a broad range of chillers with competitive applied costs and high seasonal performance guaranteed by a multiscroll design.
